AI Article Synopsis

  • Mycoplasma pneumoniae could lead to kidney issues in kids, but severe cases like glomerulonephritis are rare; this report presents an unusual case in a 3-year-old girl.
  • The girl experienced nephrotic syndrome and poor kidney function, with her serum C3 complement levels initially low but normalizing after treatment.
  • Treatment involved high-dose steroids, plasmapheresis, and additional medication, resulting in remission and improved kidney health, but controversy exists regarding the best treatment approach for such cases.

Article Abstract

Mycoplasma pneumoniae-associated nephritis has been reported in children with various pathological findings. It nevertheless remains an uncommon disease and, within this clinical context, endo-and extracapillary glomerulonephritis in a child has never been described. We report here a case of a 3-year-old girl diagnosed with severe crescentic glomerulonephritis associated with M. pneumoniae infection who presented with nephrotic syndrome and impaired renal function. The serum C3 complement level was initially low but returned to normal after 1 month. Two courses of three methylprednisolone pulses were administered in association with plasmapheresis and, secondarily, mycophenolate mophetil. This treatment regimen led to disease remission and a favorable renal outcome at the 6-month follow-up. However, the treatment guidelines in this situation remain debatable.

  • The primary pathogen causing community-acquired pneumonia in children, which can lead to complications like acute pancreatitis, accounts for 10%-40% of cases.
  • A case study of a 4-year-old girl with symptoms including fever, cough, and abdominal pain revealed elevated inflammatory markers and abnormal pancreatic enzyme levels.
  • After ruling out other causes, the infection was confirmed as the trigger for her acute pancreatitis, and she recovered after treatment with macrolides and glucocorticoids, highlighting the importance of considering pancreatitis in similar patients.

Mitigation measures aimed at curbing the transmission of the severe acute respiratory syndrome coronavirus 2 effectively suppressed the occurrence of many respiratory infections other than coronavirus disease 2019. Several infections experienced a resurgence following the relaxation of non-pharmaceutical interventions, surpassing pre-pandemic levels in Taiwan. This phenomenon, known as immune debt, primarily affected respiratory infections in young children, including respiratory syncytial virus (RSV) infection.

Key Clinical Message: Mycoplasma myocarditis is a rare but potentially serious condition that can cause inflammation of the heart muscle, leading to arrhythmia and heart failure. It is important to consider this condition in the differential diagnosis of young patients presenting with unexplained signs of heart failure and SVT, even in the absence of signs of myocardiocytolysis and extra-cardiac disease.

Abstract: infections are often underdiagnosed as a great proportion of patients remain asymptomatic, pauci-symptomatic, or exhibit varying presentations.
